NM03 – Simulation of Near-IR and Mid-IR Cascade Raman Microlasers Based on Bismuth-Modified Tungsten-Tellurite Glass

Anashkina E. A., Andrianov A. V.

We theoretically investigate cascade Raman generation in bismuth-modified tungsten-tellurite glass microlasers, for the first time for microcavities based on TeO2 glasses. The calculated results demonstrate the opportunities of CW Raman generation in the near-IR and mid-IR ranges with CW pump at the wavelength of 1.55 μm. The predicted wavelengths are 1.81 µm, 2.17 µm, 2.70 […]

P04 – Numerical modeling and experimental verification of advanced methods for characterization of broadband optical pulses and optical frequency combs

Andrianov A. V., Anashkina E. A.

We propose novel linear method for measuring ultrafast pulse trains with extremely high pulse repetition rates that are commonly generated in nonlinear microresonators. The method combines single-shot spectral interferometry with the reference pulses and an advanced version of the frequency resolved optical gating algorithm to reconstruct the initially unknown reference pulses.

P12 – Design and Simulation of Temperature Sensors Based on Thermo-Optical WGM Shifts in Silica and Non-Silica Glass Microcavities

Marisova M. P., Andrianov A. V., Anashkina E. A.

Sensing applications of dielectric microcavities with whispering-gallery modes (WGMs) have been actively studied in the recent years. Here we investigated theoretically temperature microsensors based on different glasses, including common silica glass, as well as special germanate, tungsten-tellurite, arsenic sulfide and arsenic selenide glasses. We developed numerical model describing sensing characteristics of the considered microcavities. We […]
